Pfeiffer - Model PGS-P Series - Programmable Pump Control Devices - Brochure

The programmable pump control PGS-P assigns from the pneumatic pressure sensor PNA and bubble tube supplied pressure to a level with the unit m. The zero point (0.00 m water column) can be programmed in accordance with submerged sensor. Scaling for the level, is either via the maximum value from the transducer (2.50, 5.00 or 9.99 m) or via the actual value (momentary value). The scaling is defined in steps of tenths or hundredths. The indicator value is calculated according to the input power and the scaling that is set. It is also possible to provide a scaled percentage indicator. The value of the analogue output changes in accordance with this scaling whereby 100% corresponds to 20 mA or 5/10 V at the output.
